floating point support

Hi,

I'm dealing with some images whose pixels are encoded in floating point values. Would it be possible to manipulate such images using Magick++?
I believe this question could be rephrased as does Magick++ have floating point pixel support?

Thanks,
Oguz

floating point support

After delving into the c files, I've found that imagemagick doesn't deal with floating point data the way that I need. It is possible to construct an image from a floating point array, but internally imagemagick converts the floating values into integer types (char, short, int) depending on the QuantumDepth.

I need the data to stay as floating point all throughout the loading, manipulating, and saving steps. So unfortunately, it seems, imagemagick doesn't give full support to floating point images.

Cheers,
Oguz
